tMod is dedicated server software that allows you to write plug-ins that hook the events that you describe, their forums have some tutorials that get you started. Given that you directly log the hooks and only need single conditions on perhaps the mobs being killed, it shouldn't become to complex...

Parsing is not a problem, I can write my own. Do you know where I can find more information about the output format and content?

@Drake The output is... well, the output, but in a text file instead of on your screen. As far as content goes, aside from the usual "saving world data" / "settling liquids" stuff, it's only player log-ins and chat messages I'm aware of. Death messages and boss fights are definitely not displayed.
